Well, thanks again!! Talking about what resources of LCC I use in example, in the first tune "Sagrado Corazón", in the first round I opted to beguin with some "traditional" stuff, most of it are pentatonics in all forms, but in the most of the tune, which harmonic structure is very simple: Db7/G7/FMaj#11/FMaj#11 Db7/G7/FMaj#11/FMaj#11 E9/E9/ B7/B7 Db7/G7/FMaj#11/EbMaj#11I use (I share with you one option to figure it out): F Lydian Augmented in Db7(taking this chord like a +V of F) and the same scale over G7 (taking this chord like a II of F) and F Lydian b7 for FMaj#11. This for the first line of the tune. Then I use Ab Lydian Auxiliary Dimished for Db7 (taking this chord like a IV Secondary Modal Genre of Ab) and the same scale over G7 (taking this chord like a VII of Ab) and Bb Lydian over FMaj#11 (taking this chord like a Vh of Bb). Then I use D Lydian Auxiliary Dimished Blues over E9 (taking this chord like a II of D) and A Lydian Auxiliary Dimished over B7 (taking this chord like a II of A). And in the last line I return to F Lydian Augmented over Db7 and G7 and Eb Lyd over Eb#11. This is it....
